<P>
To maintain the modularity and readability of large programs, Data Explorer
provides two tools that allow connections between input and output
tabs of separate modules without the use of a visible
connecting line.
These tools, Transmitter and Receiver, allow you to separate visual
programs into logical blocks.
For example, the output of several logical blocks can be transmitted to
another block that receives them, collects them, and produces
an image.
<P>

Receivers and Transmitters can also be used to communicate information
between pages in the Visual Program Editor (see <A
HREF="usrgu041.htm#HDRVPEPAGE">"Creating pages in the VPE"</A> in
<I>IBM Visualization Data Explorer User&#39;s Guide</I>). Pages are a valuable
way of structuring complex visual
programs into logical blocks.

<P><B>Note: </B>Macros provide another way of structuring visual programs in
logical blocks (see
<A HREF="usrgu044.htm#HDRMACROS">7.2 , "Creating and Using Macros"</A> in <I>IBM
Visualization Data Explorer User&#39;s Guide</I>).
<P>
To remotely connect input and output tabs&#58;
<OL>
<P><LI>Select a Transmitter tool (in the Special category in the tool
palette) and place it near the output tab of the module that
is to be "connected."
<P><LI>Connect the module&#39;s output tab to the Transmitter&#39;s
input tab.
<P><LI>Select a Receiver tool (also in the Special category), and place
it near the input tab of the other module that is to be
"connected."
<P><LI>Connect the Receiver&#39;s output tab to the second module&#39;s
input tab.
<P>
The Transmitter and Receiver are now connected.
</OL>
<P>
The Receiver automatically assumes the same name as the Transmitter.
More than one Receiver can be connected to a single Transmitter and they
assume the same name until a new Transmitter is placed on the
VPE canvas.
<P><B>Notes: </B><OL>
<P><LI>To change the name of a Transmitter and Receiver, use the
<TT><STRONG>Notation</STRONG></TT> field of the appropriate
configuration dialog box (see
<A HREF="usrgu041.htm#HDRUCB">"Entering Values in a Configuration Dialog
Box"</A> in <I>IBM Visualization Data Explorer User&#39;s Guide</I>).
Changing the name of a Transmitter changes the name of all the Receivers
connected to it.
Changing the name of a Receiver affects only that receiver.
<P><LI>For more information see <A HREF="usrgu041.htm#HDRTNR">"Using
Transmitters and Receivers"</A> in <I>IBM Visualization Data Explorer User&#39;s
Guide</I>.
</OL>
<P><STRONG>Example Visual Programs</STRONG>
<P>
Many of the example visual programs use receivers and transmitters,
including:
